Digger derrick fourth section
The insulated, retractable 4th section is made from fiberglass, and it replaces a non-insulated, steel 4th section on previous models. The section was designed to allow crews to be able to set poles and perform line work with an 80-foot digger derrick. The section is designed to extend and retract in minutes using the winch line. It balances on a series of boom extension rollers. It was designed to be retractable to protect the section from potential damage when not in use. For more information, visit www.terex.com/utilities.
